Letters Patent No. 64,583, dated May 7, 1867.

IMPROVED MAGBINE ron onrrnte SHEET METAL TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES H. Scuunnus, of Newark, in' the county of Essex, and State of New Jersey, have invented a. new and useful Improvement in-Tcols for Cutting Motel and I do hereby declare that the following is at full, clear, and exact description thereof, which will enable those skilled in the art; to make and use the some, reference being had to the accompanying drawing, forming a. part of this specification, in which-- Figure 1 represents a, front elevation of. this invention.

Figure 2 is 'a. horizontal section of the cutting die.

Similar letters of reference in both views indicate corresponding parts.

This invention relates to t tool which is intended patrticulnrly for cutting sheet metal or hoop iron in the proper form or shape for satchel-frames, travelling-bag fraimcs, and other articles of n similar nature. The invention consists in constructing the die or female port of the cutting tool (and, if desired, also the knife or male part) out of three or more parts, in such a manner that by changing the middle piece (or pieces) for such of greater or less length, the length of the blank. to be out can be varied, and the same end pieces cam he used for cutting blanks of every desirable length. The die is made arched or convex, so that the tool begins to out; from the centre, 'and the sheet metal or other matcriahivhile being cut, hns a tendency to crowd thc'die towards the centre, and consequently the several parts of said die are prevented from being forced apart.

Arepresents the female part. or die of my cutting tool, undB the male part or knife. For cutting out blanks for satchel-frames, or other articles of a similar nature, where a. number of pieces of (liiicrent lengths are required to make up a. set, the most difl'icult pnr ts to be formed, endthose requiring the largest quantity of steel,nre the ends, which are rounded and of the proper shape to form the hinge-joints oi the frames, while the intervening rectilinear part, which simply serves to cut the metal, is easily made and requires a. comparatively small quantity oiv steel. For this reason it is desirable that the same end pieces can be used for cutting out hlunks of difierent length. This object is obtained by making the die in three (or more) parts a a. b, the parts a a-being thc'end pieces, and the pert b the intervening rectilinear piece. :Tiicse parts are secured to the tool-holder C by means of scrcwsw, or in any other suitnhlc'mnnncr, and if the die A is in position the ends of the middle piece 6 come close up to the ends of the outer or end pieces a a, us clearly shown in fig. 1 of the drawing, and the whole die acts as if made out of one solid piece. When it is desired to cut a, blank oi greater or less length, the middle piece 6 is removed and replaced by one of thedesired. length, and after the die has been readjusted and the knife changed, the operation of cutting is continued as before, with the snme-endpieccs .a a. If desired, the knife B'muy also be made in three parts, so that the same end pieces can he used for blanks. of difi'erent length, and the cost of a, set of dies ancl knives for cutting the-various sizes of satchel-frames, or other similar articles, is materially reduced. The die A is made arched or convex, as clearly shown in fig. 1, so that it begins to act on the material to bc cut froin' the centre and by the action of said material while being cut the several parts of the die are prevented from spreading, since by reason of the arched shape oi the tool the material during the operation of cutting has a tendency to crowd the several parts of the die towards the i centre, instead of forcing them away from said centre and from each other.

What I claim, and desire to secure by Letters Patent, is

The arrangement of the parts a a 6, formed as shown, and secured to the tool-holder C, in combination with, the knife B, constructed and operating substantially as and for the purpose described.
